I'd like to get Visa for Macau and HK. advise me what sort of doc I need and how much it costs.

You just need to apply for the entry permit from Chinese embassy in Myanmar. It requires your passport, filled application form and two passport photos. As for the cost, you'd better consult with the embassy because it doesn't specify this on its official website.

If you have valid Myanmar visa/resident permit, you enjoy 7 days free stay in Macau. If you plan to stay longer, you should ask for extension after you arrive.
